In the mystical fantasy world, Chen Chang'an was confined to the forbidden library as soon as he arrived,
The sky literally started falling from the very beginning.
Fortunately, at that very moment, his system awakened,
All he needed to do was to read scriptures, and he would keep getting stronger.

Chen Chang'an stepped out of his seclusion one day, looking at the heavenly gods and buddhas scattered across the sky.

That day, he swung his sword and parted the heavens, ever since then, Heaven belongs to Heaven, Earth belongs to Earth!

He was already at the Ninth Stage, having consecutively become a Supreme Saint of Heaven and Earth, a Daluo Immortal from all heavens, and the Endless Primordial Demon from the Demon Gate; these three paths of conquest he had undertaken.


In this world, what Heavenly Venerate could he not kill?


He jovially remarked that the last one to claim this title seemed to have his True Spirit suppressed in the boundless Netherworld even at this very moment.


Tortured every day by the cycle of life and death!


So, how could the Overturning Heavenly Venerate possibly hold up against him?


Accompanied by a heartbreaking scream from the Overturning Heavenly Venerate, the terrifying death blow was delivered onto him instantly.


In an instant, a terrifying explosion resounded throughout Heaven and Earth.


The violent shockwave caused the Overturning Heavenly Venerate to be directly obliterated in mid-air.
